Season Two is the second season of the Mairimashita! Iruma-kun anime series is currently airing, started from April 17, 2021, and runs for 21 episodes. The season was announced by original creator Osamu Nishi on Twitter after the airing of the first season's final episode.
Suzuki Iruma, human and deeply non-aggressive, one day becomes the grandson of the great demon Sullivan. Doted on beyond belief, Iruma starts school where "Grandpa" serves as the chair... and finds, to his surprise, that he enjoys life there with Asmodeus, Clara, and the rest of his demon classmates. But just when Iruma thought he'd fitted in, there's more trouble ahead! A ring begins to talk, and Iruma... goes bad?! Iruma's chaotic, demonic life at school continues! 
Most of the core staff that had worked on the first season has been retained in the same respective roles, with a notable exception arising from Yumiko Hara being credited as a character designer instead of Keiko Yamamoto. Yumiko Hara previously served as the chief animation director for all of the first season's even-numbered episodes, in addition to having done character design work on Cute High Earth Defense Club LOVE! LOVE!.Bandai Namco Pictures is credited as the studio in charge of producing the animation, while NHK and NHK Enterprises are credited as producers. This season will remain in the same time slot that Season One had previously occupied, airing every Saturday at 5:35pm in Japan on the NHK Educational TV (NHK-E) station.
All staffs from the first season are confirmed to return as well.
